What should I do with my hot tub in summer? 

What you do with your hot tub in summer is completely your choice.

We find that some people decide to drain it and keep it out of use, if they are going to be travelling over the holidays. 


On the flip-side, there are plenty of hot tub owners who spend a lot of time at home over the summer and decide they are going to be making full use of their garden oasis.

How to prepare my hot tub for summer use 

Using your hot tub during summer can bring a lot of joy, invigoration and relaxation. It may require a little bit of planning in order to ensure the smooth running of your tub during the warmer months. We

recommend you follow these 8 steps:

Step One - Clean

Start by draining the hot tub completely and give it a thorough cleaning.

Use a non-abrasive cleaner such as Jacuzzi® Surface Cleaner to scrub the shell, jets, cover, filters and anything in between. Remove any debris or dirt that may have accumulated during the winter months. 


Step Two - Inspect and replace parts:

Check all the parts of your hot tub, including the cover, seals, and gaskets. Ensure that there are no cracks or leaks that need repair. 

You may want to consider booking a hot tub service, as an engineer can check and replace any components.

Step Three - Refill the tub:

The key to clearer hot tub water is that you change it every 3 months.

If you drain and refill your tub before summer, you can have fresh water for some fun in the sun! 

-Expert tip: A pipe flush will ensure crystal clear water!

Step Four - Drop the temperature:

Once it is refilled, drop the temperature on your hot tub’s settings to around 34°C (if desired). 

Warmer weather means that the sun itself can help to heat up your hot tub water, so you can save yourself some money on your energy bills. 


Step Four - Balance the water chemistry:

Whether you decide to do a water change or not, make sure you test your water using a reliable test strips or an electronic water tester like SmartPod.

This will check the pH, alkalinity, and sanitiser levels. Adjust the chemicals accordingly to achieve the recommended levels.

Proper water balance is crucial for maintaining clear and safe water. 


Step Five - Run the filtration system:

Turn on the filtration system to circulate and clean the water regularly. Ensure that the filter cartridges are clean and in good condition. If necessary, replace old filters with new ones. 


Step Six - Check the cover:

Ensure that your hot tub cover is in good condition.

Clean the cover and ensure it fits properly to preserve heat and energy efficiency. 


Step Seven - Consider upgrading or adding accessories:

If desired, this is a good time to consider upgrading or changing accessories to your hot tub.

As an example, upgrades and accessories that Jacuzzi® offer includes SmartTub®, steps, cover lifters, and

HydroSoothe™ pillows.


Step Eight - Regular maintenance:

Throughout the summer, continue to regularly test and balance the water chemistry and maintain filters.

How to prepare my hot tub for being away in summer

Do you spend a lot of time away from home in the summer? If you find yourself using your hot tub sparingly or not at all during summer, you may want to turn on vacation mode on your SmartTub® app, if you own a Jacuzzi® Hot Tub.

The hot tub will turn down a few degrees so necessary filtration cycles can run, saving you up to 25% on standby costs.

The other option is to turn your hot tub off.


Preparing your hot tub to be shut down involves several steps to ensure it remains in good condition, until it is ready to be used again.

Here's a step-by-step guide you can follow:


Step One - Clean the hot tub:

Drain the water from the hot tub and thoroughly clean the interior using a non-abrasive cleaner.

Any bacteria left on the surface could build up over time. 


Step Two - Flush the plumbing system:

To prevent any stagnant water or contaminants from causing damage, flush the plumbing system.

You can do this by connecting a hose to the water intake and allowing it to run for a few minutes until the water is clean. 


Step Three - Remove and clean the filter(s):

Take out the filter(s) and give them a thorough clean.

Use a filter cleaning solution or a mixture of water and vinegar to remove any dirt or debris.

Rinse the filters well and let them dry completely before storing them separately in a clean, dry place. 


Step Four - Fully drain the water

Remove any remaining water from the plumbing lines, pump, and heater.

Use a wet vacuum or sponge to eliminate any residual moisture.

Clean the pump and heater surfaces with a damp cloth. 

You could also consider using quick drain, a spa vac and possibly book a service to have it done professionally.


Step Five - Remove accessories and disconnect electrical connections:

Take out any removable accessories, such as headrests or cup holders. 

Disconnect the power supply to prevent any issues or accidental use during storage. 


Step Six - Cover and protect:

Use a fitted cover or tarp to protect the hot tub from dust, debris, and sunlight.

Make sure the cover is secure and properly fastened to prevent any water or pests from entering. 


Step Seven - Inspect and maintain:

Regularly check on the hot tub during shut down to ensure the cover remains intact and there are no signs of damage or water leakage.
